Preliminary experience with the St. Jude Medical Regent mechanical heart valve in the aortic position: early in vivo hemodynamic results
No full textUsefulness of the Cryolife O'Brien stentless suprannular aortic valve to prevent prosthesis-patient mismatch in the small aortic root
No full textOBJECTIVES: This study evaluated the occurrence of prosthesis-patient mismatch (PPM) after Cryolife O'Brien (CLOB) suprannular stentless valve replacement in patients with a small aortic root and its repercussions on the patient's hemodynamic status and left ventricular mass regression. BACKGROUND: The correct management of the small aortic annulus is still controversial. Small aortic prostheses can lead to a PPM, which results in high gradients with important repercussions on the hemodynamic status. METHODS: Seventy-two patients (mean age: 72.5 ± 6.2 years, 73.6% women) with a small aortic root (≤21 mm intraoperatively measured aortic annulus) had a CLOB valve implanted in the aortic position between November 1993 and July 2001 at our institution. Mean prosthesis size was 22.0 ± 0.8 mm. Patients underwent echocardiography preoperatively, at discharge, six months, one year and yearly thereafter. RESULTS: The incidence of PPM at discharge was 22.2% (16/72); 18.7% were severe (effective orifice area index [EOAI] ≤0.65 cm/m2), 43.7% were moderate (EOAI = 0.66 to 0.75 cm/m2) and 37.6% were mild (0.76 to 0.85 cm/m2). At multivariable analysis, gender (p < 0.001), age (p = 0.015), body surface area (p < 0.001) and patient's annulus index (p < 0.001) were significant factors influencing the occurrence of "transient" PPM. At one year the incidence of PPM was 0%. CONCLUSIONS: Suprannular CLOB valve yielded excellent hemodynamic results in patients with small aortic roots. This study demonstrates that PPM can be completely avoided when using the CLOB valve. The superior hemodynamics of this stentless valve are likely to be related to its suprannular design. © 2002 by the American College of Cardiology Foundation
Stentless aortic valve replacement in elderly patients
No full textObjective. Seven-year clinical and hemodynamic results of the Cryolife O'Brien (CLOB) stentless bioprosthesis in elderly patients are reported.
Methods. From 1993 to 2000, 36 patients aged >75 years had a CLOB implanted in the aortic position. Eighteen (50%) were male. All patients were monitored with serial echocardiograms performed preoperatively, at discharge, six months, one year and yearly thereafter.
Results. The 30-day mortality was 2.4% (1/36). Actuarial survival at one, five and seven years were 96.7+/-1.5, 94.8+/-2.0 and 94.8+/-2.0%, respectively. Peak and mean gradients (PG and MG) reduced and effective orifice area index (EOAI) increased over time (P<0.001). Left ventricular mass index (LVMI) reduced by 32 g/m(2) at discharge (P<0.001) and by 33 g/m(2) at six months (P<0.001) without further significant changes.
Conclusions, In our series CLOB xenograft resulted to be a satisfactory valve substitute in elderly patients. (C) 2002 The International Society for Cardiovascular Surgery

No full textChylopericardium is a rare complication of cardiac surgical procedures. We describe a 41-year-old woman who underwent orthotopic heart transplantation and developed chylopericardium early in the post-operative period. Because of unsuccessful conservative treatment (pericardiocentesis, pericardial drainage, low-fat diet with medium-chain triglycerides, and total parenteral nutrition), surgical intervention was indicated and the patient successfully underwent right-sided thoracoscopic duct ligation and partial pericardiectomy (pericardial window
